When Hilary, along with the Democrat party leadership is indicted, the full weight of the Democrat political machine will be brought to bear in the last effort to preserve what they believe to be rightfully theirs. Hundreds of thousands, maybe even millions of people will descend on Washington DC utterly convinced that they are the last line of defence against a dictatorship. That will be way beyond the ability of the police to contain. If the National Guard is brought in to keep order, the rest of the country is left understaffed - civil unrest and colossal property damage is the best case scenario. You need… an army.
How do you gather an army in the nation's capital without violating Posse Comitatus?
